IMPROVEMENT IN HS-LEAK STOPPERS.

Specification forming part of Letters Patent No. 115,715, dated June 6,1871.

To allpersons to whom these presents may come Be it known that I,WILLIAM O. DAvoL, Jr., of Fall River, of the county of Bristol, of theState of Massachusetts, have invented a new and useful or ImprovedHose-Leak Stopper; and do hereby declare the same to be fully describedin the following specification and represented in the accompanyingdrawing, of which- Figure l is a top view, Fig. 2 an end elevation, andFig. 3 a central and transverse section of the article as opened andresting upon a plane surface.

In the drawing, A and B denote two semitubular jaws, having, whenclosed, a cylindrical bore, and being hinged together at one side ofsuch, as shown at'a. Opposite to where the said jaws are so connected,one of them has a tubular standard, b, extended from it to receive ascrew, C, which goes up through such standard. The said screw has a flathead, d, as shown, in order to enable such head to be passed between andbelow two ears, c e, projecting, as exhibited, from the lower jaw. Anut, f, provided with a handle, g, extending froinit in manner asrepresented, is screwed upon the screw C. Each jaw on its inner surfacehas a thick lining or cushion, h, of India rubber or other suitableelastic water-proof material afixed to it. The formation of the head andshank of the screw being as represented, the shank, after having beenpassed between the ears e e so as to carry the head a short distancebelow them, will, after being turned ninety degrees and drawn upward soas to bring the head up against the ears, estop the screw from beingrevolved with the nut while the latter may be in the act of being turnedaround on the screw.

In applying the lealnstopper to a burst hose it is intended for it toembrace the saine and cover the hole that may have been made by thebursting of the hose, after which, by means of the screw and nut, thewater-proof elastic cushions of the jaws are to be clamped upon thehose. l

The leak-stopper, made as described, has been found to be very eiiicientin use. It is well-known that the bursting of the hose of a dre-engineis a common occurrence, and frequently occasions great inconvenience andloss. It therefore becomes a desideratum to have some simple means athand for im mediately remedying the evil. That which I have inventedcompletely does this.

I claim- The hose-leak stopper, constructed as described-viz., of thetwo semi-tubular jaws A B, hinged together, their rubber linings orwater-proof cushions h h, and means, as explained, for clamping suchjaws or the linings upon a hose, such means being the ears e c, thescrew C, the tubular standard b, the nut f, and its handle g, all beingas represented.
